1. Color and shine

24K gold has a tone intense yellow and warm, much brighter than 18K or 14K.
It does not fade and maintains its brightness over time, even without chemical treatments.

2. Malleability and ductility

AND the most malleable metal in the world: just one gram of pure gold can be reduced to a wire over 2 km long or to a very thin sheet.
This feature makes it perfect for fine goldsmith work or gilding, but also for technological applications.

3. Stainless and unassailable

24K gold It does not oxidize, rust or corrode, not even in contact with air or water.
It's a metal chemically inert, therefore it does not cause allergies or skin irritations.

4. Density and specific weight

With a density of approximately 19.3 g/cm³, is among the heaviest and most compact metals in nature.
This makes it easily distinguishable from imitations or plated metals.

Difference between 24K, 18K and 14K gold

24K gold, although the purest, it's also the most tender.
